The New INS-DH-OEM Seamlessly Integrates the Honeywell HG4930 Inertial Measurement Unit (IMU) into a GPS-Aided Inertial Navigation System (INS) to Provide High-Accuracy Orientation, Position, Velocity, and Timing (OPVT) for Land and Aerial Systems

The newly released INS-DH-OEM is a high-accuracy INS designed for easy integration into custom enclosures and higher order integrated system applications.

Paeonian Springs, VA: The latest addition to Inertial Labs’ expansive line of INS solutions, the INS-DH-OEM, is a great example of a case in which combining the performance of the Honeywell HG4930 and Inertial Labs’ sensor fusion expertise can be a perfect fit for certain applications. Consisting of 3 axes each of high-precision accelerometers and gyroscopes, the accuracy of the HG4930 plays a key role in the exceptional performance of the INS-DH-OEM. With input from the IMU, the INS-DH-OEM can boast a pitch and roll accuracy of 0.015 degrees RMS for dynamic applications, and a pitch and roll accuracy of 0.01 degrees for motionless applications. Inertial Labs is excited to debut the proven, rugged, and reliable HG4930 in our line of high-performing INS solutions.

Another key factor in the performance of the INS-DH-OEM is its use of the Novatel OEM7720 dual antenna GNSS receiver. The OEM7720 is an all-constellation, multi-frequency heading and positioning solution with TerraStar PPP correction services and advanced interference mitigation features. With aiding data from the OEM7720, the INS-DH-OEM features a 2-meter baseline heading accuracy of 0.05 degrees RMS for both static and dynamic applications. As a result, the INS-DH-OEM is a high-performance solution in line-of-sight (LOS) and beyond line-of-sight (BLOS) antenna pointing applications. A reliable solution in varying environments, the OEM7720 ensures that the INS-DH-OEM is outputting the most accurate GNSS-aided data by supporting GPS, GLONASS, BeiDou, Galileo, NavIC (IRNSS), and QZSS constellations.

The INS-DH-OEM can be applied in a wide range of aerial applications such as remote sensing, flight control, and photogrammetry in which the INS-DH-OEM provides accurate positioning, navigation, and timing (PNT) data for multi-rotor drones, fixed-wing drones, and other UAVs performing these tasks. This data is paramount in the accuracy of these applications’ deliverables such as point clouds, orthomosaics, and photogrammetric plots. With a weight of 280 grams and 85.7x62.5x52.0 mm dimensions, the INS-DH-OEM is a lightweight and compact system that can be easily fitted with custom enclosures or integrated into higher order systems such as LiDAR payloads. The INS-DH-OEM is compatible with scanners from many of the industry-leading LiDAR manufacturers including: Livox, Velodyne, Ouster, and Quanergy. This adaptability, coupled with top-of-the-line subcomponents and Inertial Labs’ sensor fusion expertise, make the INS-DH-OEM the ideal solution for UAVs, UGVs, Antenna Pointing, and many more applications.

With over 20 years in the positioning and orientation sensor industry, Inertial Labs is growing its catalog of innovative solutions at the best value, smallest size, and lowest power consumption in their class. From commerce and industry to government, defense, and aerospace, Inertial Labs is at the forefront of developing and customizing products for exciting technologies, solving today’s problems, and unraveling those of tomorrow.
